Concrete block setting form

ABSTRACT

A concrete block setting form comprising a pair of side boards which are secured on an initial course of blocks by quick release clamps, to hold one or more blocks in precise alignment. The side boards have ribs which spaced the block or blocks, so that mortar or concrete poured in place will form seamed joints of proper thickness.

VICTOR B- CHERNIAK ah/6 ATTORNEY CONCRETE BLOCK SETTING FORM BACKGROUND OF THE INVENTION In the manual construction of a concrete block wall, the usual technique is to seat each block on a layer of mortar or concrete applied to the previous course of blocks. Alignment is maintained by using a stretched line and a level, considerable skill being necessary to construct an accurate wall. Jigs and supports have been devised to hold a number of blocks in position, sometimes a complete wall panel, while mortar is applied, by pouring or from a nozzle. Such jigs are elaborate and require much set up and removal time.

A simple alignment and locating aid for use in manual wall construction would be a great advantage.

SUMMARY OF THE INVENTION The block setting form described herein comprises a pair of opposite handed side boards which areheld on an initial course of blocks by quick release clamps, to hold one or more blocks in place. The boards have ribs which support each block in spaced relation from the other blocks at the correct spacing for a seam of mortar, which is poured through the hollow cores of the blocks and fills all spaces to bond the blocks securely together. After pouring, the clamps are removed and the form moved to the next position, no tools being necessary to apply and release the clamps. The form will hold full or half blocks and is thus adaptable to corner construction. With the form, a true wall can be built rapidly and, when dismantled, the form can be stored flat in a minimum of space.

The primary object of this invention, therefore, is to provide a new and improved concrete block setting form.

Another object of this invention is to provide a new and improved concrete block setting form which holds each block in alignment and proper spaced relation for a seam of mortar.

Another object of this invention is to provide a new and improved concrete block setting form which is secured by quickly releasable, manually operated clamps.

Other objects and many advantages of this invention will become more apparent upon a reading of the following detailed description and an examination of the drawings, wherein like reference numerals designate like parts throughout and in which.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of one side board of the form.

FIG. 2 is a side elevation view of a typical wall structure with the form in use.

FIG. 3 is an enlarged sectional view taken on line 3- 3 ofFIG. 2.

FIG. 4 is a perspective view of a quick release clamp used with the form.

DESCRIPTION OF THE PREFERRED EMBODIMENT pins may be used if necessary Board 10 is shown in block in proper alignment. At one end of base rib 20 is a vertical and rib 24 extending to the upper edge 26 of the plate 16. Spaced from end rib 24 is a similar vertical spacer rib 28, at a distance equal to the length of a standard concrete block, so that a block fits closely into the open topped frame formed by ribs 20, 24 and 28. Another similar end rib 30 is spaced from rib 28 at a distanceequal to the length of a half block, which is normally the same as the width of a standard block.

The side board as shown is thus adapted to hold a full block and a half block for versatility. However, other configurations may be used for a single block, or two or more full blocks, without the structure becoming unwieldy to handle. The ribs may be attached to the plate in any suitable manner, or molded or cast in a unitary structure. 1 r

Clamp pin 14 is a rod-like element havinga stem 32 with a fork 34 at one end, in which a tip portion 36 is pivotally mounted by a hinge pin 38. When the tip portion and stem arein axial alignment, the pin is of constant diameter to pass through holes 40 through the side board near the lower edge of base rib 20. Any suitable number of holes maybe used for sufficient clamp pins to hold the assembly firmly. At the other end of stem 32 is a fork 42, in which a locking lever 44 is pivotally mounted on a hinge pin 46. Lever 44 has a cam 48 which locks the clamp pin, as hereinafter described.

In building a wall with the form, a base course 50 of blocks 52 is constructed on a suitable foundation in the usual manner. For the second course of blocks, the side boards 10 and 12 are placed on opposite sides of the lower course, with the base ribs 20 resting on top of the blocks and clamp pins 14 extending between the boards, with tip portions 36 turned horizontally to hold the assembly loosely. The lower portions of plates 16 extending below the base ribs, form clamp flanges 54 which grip the lower blocks. As shown in FIG. 2, the plates also have end flanges 56 extending beyond end ribs 24 to grip the adjacent block 58. A block 60 is then inserted between the side boards and clamp pins 14 are locked by swinging levers 44, so that cams 48 clamp the side boards together. The side boards are securely held by one or more C clips 66 straddling the top of the assembly, the clip having legs 68 which grip the outside of the boards. A leaf spring 70 is mounted in one arm 68 to provide a resilient gripping action, the other arm having an inset roller 72 to reduce friction when removing the clamp and avoid disturbing the blocks. Alternatively, both arms could have spring elements 70, the clip could be made adjustable for different block widths. The ribs hold block 60 spaced above the lower course and spaced horizontally from block 58 at the required distance for a proper seam or mortar joint, indicated typically at 74.

Mortar or concrete is poured in through the hollow core 62 of block 60, as indicated by the directional arrow in FIG. 3, and between blocks 58 and 60, and fills up the spaces under the block being set. To reduce the amount of concrete needed and leave space for reinforcing steel and other structure, core tubes 64 are placed in the hollow cores through the blocks and are withdrawn or raised as the wall progresses. After pouring the concrete, locking levers 44 are swung out to release earns 48, the tip portions 36 are turned into line with stems 32 and the clamp pins are withdrawn, then the C clips 66 are pulled off, allowing the side boards to be removed. Normal slumping of the wet mortar will close the small holes left by the clamp pins.

It should be noted that the form could also be dimensioned for setting bricks or special blocks, the mortar being injected between and below the bricks by any suitable means.

In practice, assembly and removal of the form is rapid and one or more blocks may be placed simultaneously to speed progress. Accurate alignment can be maintained with minimum references, such as lines and levels.

Having described my invention, I now claim.

1. A concrete block setting form, comprising,

a pair of similar, opposite handed side boards each having a base rib on the inner face thereof to rest on the top edge of a set course of blocks, with the side boards in upright spaced relation on opposite sides of the blocks,

said side boards each having spacing ribs extending perpendicular from said base rib to the upper edge of the side board, at a spacing equal to the length of a block to be set, and forming, with the base ribs, an open topped frame with the upper inner faces of the side boards unobstructed to allow insertion of a block vertically into the open topped frame,

said ribs having a thickness equal to the thickness of a required mortar seam,

said side boards having flange portions extending outwardly beyond said ribs,

and releasable clamp means interconnecting said side boards.
